BOBBlN-CLUTCHING MEANS FOR ROTATABLE SPINDLES.

SPECIFICATION forming part of Letters Patent No. 776,163, dated November29, 1904.

Application "filed $eptcmbc1 28,1904. Serial No. 226,389. (No model.)

To all whom, it 777/1711] concern:

Be it known that I, VVILLIAM E. ALLEN, a citizen of the United States,and a resident of Salem, county of Essex, State of Massachu- 5 setts,have invented an Improvement in Bobbin-clutching Means for RotatableSpindles, of which the following description, in connec* tion with theaccompanying drawings, is a specification, like characters on thedrawings I0 representing like parts. 7

This invention has for its object the production of novel and simplemeans for holding a yarn-receiver or bobbin in proper position upon aspinning or other rotatable spindle and to effect rotation of the bobbintherewith.

The several novel features of my invention will be fully described inthe subjoined speci- [ication and particularly pointed out in the claimsappended thereto.

Figure l is a side elevation of a portion of a rotatable spindle withone embodiment of my invention applied thereto, the base or head of abobbin being shown in section and elevation in operative position. Fig.2 is a cross-section on the line 2 2, Fig. 1, looking down; and Fig. 3is a plan view of an attachment for the head of. the bobbin, to bedescribed.

In Fig. 1 I have shown a portion of a spindle A, having awhirl Wattached thereto by a sleeve to, the construction common in a well-knowntype of sleeve-whirl spindle. The sleeve is provided with a plurality oflongitudinal grooves or seats 10*, four being shown in Figs. 1 and E2,symmetrically disposed with relation to the axis of the spindle. In eachseat I mount an elongated and slightlytapered clutching member 1, madeof metal and fulcrumed near its lower end on a pin 2,

driven into the sleeve across the seat, so that the clutching memberscan move in an out in radial planes. The outer edge of each member isrounded off at its upper end at 3, and the projecting portion 4 belowthe fulcrum serves as a stop to limit outward movement of the memberwhen such portion engages the bottom of the seat. Each member isprovided at its lower end with means to vertically support the bobbinand also to externally engage the head thereof and effect its 5 rotationwith the spindle. To this end each member 1 is provided with an J-shapedfoot 5 6, the part 5 projecting radially and the part 6 being upturned,(see Fig. 1,) the foot joining the member adjacent its fulcrum.

The yarn-receiver or bobbin B is of substantially well-known form, itshead 6 having a chamber 1) to receive the sleeve 10 and clutchingmembers 1 when the bobbin is applied to the spindle, the end of the headat such time resting upon and being vertically supported by the radialportions 5 of the feet.

The weight of the bobbin acts to depress the feet and press the members1 outward into internal engagement with the walls of the 5 chamber 7),and this engagement is enforced. by centrifugal action when the spindleis rotating.

ln 'order to eii'ect a positive drive for the bobbin, 1 provide the headwith a series of ex- 7 ternal projections, and this is conveniently doneby forcing thereon a metal ring 7, Fig.

3, having radial lugs or projections 8 upon its peri 'ihery.

The upturned extremities 6 of the feet ongage the sides of theprojections, as shown in Fig. 1, and thus cause the bobbin to rotatepositively in unison with the spindle.

A very simple and effective clutch is thus provided, its holding actionupon the bobbin 8O increasing as the weight of the yarn mass thereonincreases, holding the bobbin down in proper position and rotating itpositively with the spindle.

Having fully described my invention, what 5 I claim as new, and desireto secure by Letters Patent, is

1. A rotatable spindle having an attached sleeve, a series of elongated,upturned bobbinclutching members fulcrumed thereon at 9 their lower endsand adapted to enter the chambered head of a bobbin, a detachablebobbin, having external radial projections on its head, and meansconnected with the clutching members to vertically support the bobbinand also engage the projections thereon and positively rotate thebobbin.

2. A rotatable spindle, a plurality of elongated, upturned clutchingmembers fulcrumed at the lower ends thereon, to swing in radial planes,each member having an I-shaped foot adapted to vertically support abobbin, and a detachable bobbin having a chambered head to receive saidclutching members and provided on the end of its head with radialprojections to be engaged by the extremities of the feet, to positivelyrotate the bobbin with the spindle.

3. A rotatable spindle, a plurality of elongated, upturned cl utchingmembers fulcrumed at their lower ends thereon, to swing in radialplanes, means on said members to receive the head of a bobbin andpositively engage the exterior thereof, to vertically support and drivethe bobbin positively with the spindle, and a detachable bobbin having ahead chambered to receive the clutching members.

i. Arotatable spindle, a whirl, a sleeve connecting them and having aseries of longitudinal seats, elongated clutching members fulcrumed attheir lower ends in said seats and movable in radial planes, each memberhaving an |-shaped foot, and a stop below its fulcrum to limit outwardswing, the clutching members being adapted to internally engage, and thefeet to externally engage and also vertically support, the head of abobbin.

5; A rotatable spindle, a plurality of elongated, upturned clutchingmembers fulcru med at their lower ends thereon, to swing in radialplanes, and means on each member below its fulcrum adapted to engage andsupport vertically a bobbin when applied to the spindle, the weight ofthe bobbin acting through said means to press the clutching membersoutward into internal engagement with the bobbin.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
